neated at the base, and.obtuse at the apex, smooth. Racemes terminal, stalked, 
pyramidal, straight; pedicels 
hoary and villous. Calyxes 
campanulate, 3-lobed ; lobes 
tomentosely ciliated. Corolla 
glabrous, but the carina is 
clothed with silky villi. Le-

An erect woody shrub, re- 
sembling alaburnum. Dal- 
matia, in woods on moun- 
tains. Height 2 ft. to 3 ft.; 
p 
6 ft. to 8 ft.1n gardens. In- My i p 
troduced in 1837. Flowers AA Y 
yellow, fragrant; June and 
July. Legumes brown ; ripe 
in October. 
The racemes are erect, and 
do not droop even when in 
fruit. The seeds are still more 
poisonous than those of the 
common laburnum, and the i 
scent of the flowers causes S x 
headach. The milk of the B4Be_ Cs eaus: Welgenit: 
goats which feed upon the flowers, Baron Welden observes, produces the same 
effect, only more severely, upon those who drink it.
